Using COBOL for Web Services

Web Services interface
COBOL can provide or request Web Services, using architectures based on SOAP (Simple Object Access Protocol) or REST (REpresentational State Transfer). Data in the interface to such services is typically represented in JSON (JavaScript Object Notation) or XML (eXtensible Markup Language). The following information describes COBOL and other facilities that can be used to generate and consume JSON and XML.
Processing JSON input
You can process JSON text input in a COBOL program by using the JSON PARSE statement. The statement identifies the source data item containing the JSON text, and the receiving data item that is populated by the parser.
Producing JSON output
You can express COBOL data items as JSON text by using the JSON GENERATE statement, which identifies the source and output data items.
Processing XML input
You can process XML input in a COBOL program by using the XML PARSE statement.
Producing XML output
You can produce XML output from a COBOL program by using the XML GENERATE statement.
